Description
Phone, camera and wearable lines drive screws so small that inch-pounds become too coarse a unit. The CDI 1001-O-DTT torque tester works in inch-ounces instead. It reads from 10 to 100 in-oz, or 7 to 70.6 cN·m, through a 1/4″ drive. As a result, a line technician can confirm that each torque screwdriver still delivers its set value.
The O in the model name
In these CDI model names, the middle letter tracks the unit. The 1001-I-DTT reads 10-100 in-lb, while the 1001-O-DTT reads 10-100 in-oz. The digits match, yet the loads differ a lot, because 16 in-oz make 1 in-lb. So this tester tops out near 6.25 in-lb. Order the wrong letter, and the unit will not cover your tools.
Tools that suit the CDI 1001-O-DTT torque tester
- Torque screwdrivers on PCB, camera module and display assembly.
- Preset drivers on hinge, bezel and battery cover screws.
- Spare and repaired drivers before they return to the line.
- Drivers in supplier tool kits at incoming inspection.
Choosing test points
On the 1001-O-DTT, check each driver at the value it uses in production. For adjustable drivers, also test near the low and high ends of their working band. Readings on any scale tend to be most stable away from the very bottom. Therefore a driver set at 15 in-oz may deserve a closer look than one at 60 in-oz. If your fleet runs above 100 in-oz, the 8001-O-DTT covers a wider band.
A shift-start routine
Place the 1001-O-DTT on a stable bench and confirm it shows zero with no load. Next, fit the driver, apply force slowly and note the reading. Compare it with the station tolerance, then log the result with the driver ID. Pull any tool that fails out of service, and send it for adjustment.
Bench care
Keep the tester away from dropped drivers and heavy parts. Avoid side loads on the drive, because the unit measures torque, not bending. Store the CDI 1001-O-DTT torque tester in its case when the line stops. Then send it to an independent lab for calibration on the interval your quality plan sets.

1001-O-DTT questions from electronics lines
What is 100 in-oz in N·m?
About 0.706 N·m, or 70.6 cN·m, which is the top of the 1001-O-DTT range.
Will it check a 1/4 in torque wrench?
Only if the wrench works below 100 in-oz, the 1001-O-DTT limit of about 6.25 in-lb. Most 1/4″ wrenches run higher, so pair them with an in-lb tester such as the 1001-I-DTT.
Will a calibration certificate come with it?
The listing does not say. Ask Lost in HCM which documents come with the 1001-O-DTT when you request a quote.
